3种粘接材料与氧化锆陶瓷粘接抗剪切强度的比较
Comparison of shear bond strength among three luting cements with Zirconia Ceramics
摘要
Abstract
Objective To study the shear bond strength of three kinds of luting cement materials with Zirconia Ceramics restorations.Methods Blocks of sintered Zirconia Ceramics were cut and randomly divided into three groups with 20 slices in each.After being treated with sandblasting,they were bonded to the surface of cured core-resin using three kinds of luting cements respectively,glass ionomer cement (group GIC),Panavia F 2.0 (group PF),Clearfil SA Luting (group SAC).Half of the discs in each group were performed thermal cycling (10 000 cycles between 5 and 55℃) test.The shear bond strength test were performed in each group.Results The shear bond strength (SBS) of group GIC,group PF and group SAC separately were (21.98 ± 1.78) MPa,(30.26 ± 1.73) MPa,(28.63 ±2.02) MPa before thermal cycling test.The value of group GIC was lower than other two groups significantly.The values of group PF and group SAC had no significant differences; The SBS of each group were (10.72 ± 2.03) MPa,(28.50 ± 1.54) MPa,(27.02 ± 1.79) MPa after thermal cycling test separately.The value of group GIC was significantly different from before; while the values of other groups didnt decrease.Conclusion GIC can get good bonding,but can' t last long.Resin luting cements containing phosphate ester monomercan provides a strong initial and long-term bonding strength for Zirconia Ceramics.One-step self etching adhesives provides comparable bond strength with self-etching resin luting cements,and the strength could last long.关键词
